Add rule GL033 that warns when every rule in a job's rules: block has an explicit when: never, making the job permanently excluded from any pipeline run. This is a pure static check — no if: evaluation or context required. Only rules with literal when: never trigger it; rules with no when: (defaults to on_success), when: manual, when: always, or when: on_failure are treated as reachable.
